IMPROVEMENT IN LGM PGR WEAVIG WIRE CLOTH.

-The Schedule referred to in. these Letters Patent and making part cf the same.

To all whom it ma/ I/ concern new and useful Improvements inWire-eavin g Looms and l cloherebydeclare that the followingis arfulhclear,

andI exact description of my invention, re'erence being had to the accompanying drawings, forming a part ot' this specification, and to the letters of reference marked thereon, of which drawings- Figure l -is an elevation of my improved loom. lFigure 2 is aplan of the same.

' Figures 12 are-.elevation and plan of one' of the friction-ratchetsx p i Figures 13 lareseotion and plan of-mesh-former.- j My Vinvention relates to certain improvements in Ylooms forweaving wire cloth said improvements consisting in the novel mode of constructing the shuttleY spool, whereby it is made very easy to pnt into o r take out of the-shuttle, and has also the advantage of pre venting wire onthe spool from unwinding, by reason of its elasticity; also, in the novel mode of operating the,` shuttle', also, 4in the novel construction and opera-` tion of a mesh-former, whereby -I obtain a cloth with all its meshes of precisely the same shapeand size; also, in the construction ofa fillingpresser,which acts, in combination with the mesh-former, to aid in the obtaining cfa perfect mesh; also, in the novel modev of operating said filling-presser; also, in theI novel mechanism for operating the harness which operates the wires-which constitute the warp 'of thecloth; and, lastly, in the novel inode of regulating `the rollingpup of the cloth after it has been woven.,

The peculiar utility7 of these several improvements consists in the making of u cloth with all `its meshes of precisely the same form and size, and having all the wires of which it is coinpsed free from any kinks or irregularities; also, in making asuperior article of mer-l chandise at a more rapid rate, and hence, atan expense less than that of making an inferior article on looms heretolbre used for-this purpose.

To enable otheisskilled in the art to make and use my invention, l will proceed'to describe its construc- (ion and operation.

l B B are the main sills of the machine, on which are secured'the lower frame-pieces' A A. l'

In these llame-pieces are secured the uprights C Q and E E, which have upperame-pieces F F secured 'to them, as shown. y

The cross-pieces H and J connect the upper frame` piecesF F, and outside cross-pieces G G ani M M (see iig. 5) connect the outer-uprights D D tothe main frame, the upright, D', being arranged between the pieces G and M, as shown.

The -main driving-sha L has its bearings in.. boxes 22, 22 on the lower frame-pieces A A, and power is communicated to said shaft by means of the pulley 54', y or in any other suitable manner. v i i The warp-wire drum 56 is 'hung in boxcs82,'82 on the uprights E E, i i i At the end ofthe frame, and on one end of its'axis 83, is secured the gear-wheel 59, which gears into a secondVgear-wheel, 6G, which is secured tothe axis 84' of the i'ictionwheel 61. Y Y

^ This axis 84 yruns in a box on the upright, E, (not seen in drawiugs,) and in a hole in the upright, 85, at tached to the piece AV p lI ,Around the friction-wheel 61 is' plac which is secured, at one end, to ahook, Q4, 486, which-is of the @crm shown inlfigsfland 2,'-aud is secured to the sill 1 3, while the otherend of Asaid belt G2 is attached to a sliding collar, 63 wliich worhspp andfdown on the screw-bolt G5. Y w' A spiral spring is arrangec. on the bolt 65,.as seen in iig. v1,'its upper end vbearing on a collar on said holt,

while the lower end hearsV onithe sliding collar 62?,`

A thumb-nut, 67, isnrranged on the bolt 65, below the arm S6, and the holt 'is made so as to slidefin'f holes made .inv the upper and lower horizontal partsiof the arm 86. i i

It is readily seenlthat,` by screwing up 'or u nscrew'fl ing the nut 67, the friction of the helt 62 on the wheel -61 may bevaried at pleasure, therebyregulating the rotation of thechtum 56, andcousequently the tensio "on the warp-wires.

On .the warp-,wire drum'are arranged the disks 57, 57, which are thin rings of metal, arranged perpendici ularly to the axis of' said drum, and which divid'ethesurface of said drum into several parts, on which the dii'erent warp-wires are wound,-the object being to keep each wire separate from the others, .to prevent any tangling of said wires. v 4

The w'i'np-wires pass' from the drum 56 up over the' roller 58, arranged 'on the end of uprights E E, as shown, and from here, through the loops 87, 87 in the harness N and O, the same as the warp-threads in the common loom. They arethen' passed through the spaces between the bars13, 13 ofthe filling-presses ll, (see iig.

'10,) and from thence pass betweenv the mesh-blocks 51, 151 of the mesh-former 50, (see figs. land 2.) Beyond these mesh-blocks they form a fart of the woven cloth.

by the links q as this arm V turnsA beyond vers te, said leyersare struck on the side a'rrjhs therebylcau'sing the rods' b b to recede from each othei'.

which passes over the roller 28, and around between said roller and the roller 27, thence over said roller 27 on to the receiving-roller 15,

The position of the warpovires, from the warp-wire drum 56, to the lncshdbrmer 50, is shown by blue lines in figs. 1 and?, while the movement of the woven cloth from the meshvl'ormer ou o the receiving-roller l5, is shown by blue lines in iig. il. The shuttle n is of a hole, o, with slots oo made in eachside. lhis shuttleis operated by the shuttle-bars l1- h, which have the pointed ends l if, with wings b3 t, of the same sizs'as the hole @and slotsc oP inthfe'shuttle, so that said ends lib? pass through" the holes lo in thc-shuttle, and support the saine, asseen in ligs. 1 and 2; These shuttle-bars it bare of pecnliarconstruction, being made olla tube, b, side, anda rod, h, inside`"the tube l, as shown inlig; 7,

The head ti is arrangedon 'the rod b, and the head b, up to the collar b, the distance' firom rear of head l1 to collar la being eqiialtothe length of one of 1 the holesov in the sidesol'the shuttle n, from which it'.

is readily seen thatthe end of the rod and tube b' b may he introduced into thelrcle o of the shuttle 1t, and

the shnttlebe then secured in that position, by simplyv The .shuttle-bars l1 h are arranged to slide in the supe ports p p', which are attached tothe pieces G G and D D of the liame,

q, which are attached to the flanges b, as seen in lig.

the rock-shafts t t, said rock-shafts being. hung in'boxes ti. t? on the frame-piece A, as shown by' sinnll detached plan in lig. 5.1'

I 0,11 the shaft L is arranged the centre arm V, which centre arm V will lirst strike the innerl ends'ofthe rooklevers t t, and force them down, 'as shown, thereby causing the rods b b to approach each other. Then, as' soon' thev ends ofthe rock-leaud turned up at a'contrary angle,

The adjustable plates?, 3 are arranged on the'ends of the-levers i', to compensate for anywearing at said ends.

1 on the endsf the was 1 u sie arranged uw' wheels cc,- having teeth arranged on their-edges,`and four notches, on lines at right angles to each other, on the raised rims or their faces.

A n arm, k, of the form shown, is secured to the tube bland has a spring, j, arranged as shown, the ends of said 'spring lying in the notches in the raised rim of the wheel c, thus preventing a rotation of therodb', ex-

cept when the proper power is applied.

The slides l d are of the form shown, and are ar-y ranged to slide up and down on )the outer uprights D D,- hymea'cs of the slot j, over the bolts-that secure them to the side of the up rights D, while their upper ends have ahole through which pass the rods m m,which are inserted in thetop of the uprights D, and around which which engage with the teeth on the edge of the wheels c c, and cause 'a rotation of said wheels when the slides dlareibrceddown.

The arms h h are of the form shown, and are secured at the nds of the shaft L by bolts l ljwhich :pass through slots s' `in said arms, theend of the shaft. i

These arms h vh are of such lengthjthst at each revo-- the forni shown in figs. 3, and has having a hangs, b, on its lower end'- 79of the tube h is ol the-same-shape and-size ostile,

and are caused to slide insaid suppoits 5, their other ends being securedto the. arms l11' fr of 'the rock-levers t t, which are. secured on.

their other ends' by whiclrallmrs the movement drawin are placed 'spiral springs, which serve to raise the slides d d. 1 'Y One or more pins, ce, are inserted ln the slides d d,

and screw-into holes in of the shuttle n, which .will then be intlie-cent-r of the warp, as seen in 5, while the wheels c c will be yhrougdu; up against the slides d d, ffl'hen, while the bars'b ll and shuttle n are in this positionythe arms h pins'c 'e on theteethot the wheels c c, cause a quarter turn of said wheel, (the spr-ingj sliding out of one notch, on the. raised rim-'of 'thewheel o, and springin into .thcfneit notch, to allow of`this quarter turn.

down irl-standards or guides 2, 2, attached. to the framepeces F F i The 'connecting-links on pitrnen, P and Q,fconnect theharness N and/0 to the double-crank shaft R, by the rerolutiou'of 4which the harness. are caused to move '11p avd'dowm f 1' This shaft' R is Ahung `in 'standards 55,'55, which une' secured to the. lower iiamepieces A AA-,and has the geanwheel S seemed at one end,which'whcel gears' intothe wheel'l on the shaftU. 1 f

This sha U is hung in boxes c a onthe uprights DA and D', as shown, and has secured to it the wheel V, which is a circular wheel, having four slots, 8 1, 81 ari ranged cuits periphery, which are4 on lines at right ongles to each other, and has also the pins 82, 82 arranged around at equal intervals' o n its face, in such a mannerns to'form a kind of lantern-wheel; .-Astondardplate, Y, (see fig. 1,) is secured'tothe a hole, through pressed into the slot 81- in wheel V.

'up, as seen-in fig. 8. A segment of a plaiegear-wheel, W, is secured on `the main shaft L, in such position as; to gear wi'dthe lantern-wheel Vat each revolution of the main shaft, and has secured to itan arm, Z, which isso constructed and arranged as' thatA it shall strike the lower end of fthe har X, and cause the saine to slide'np, thereby the piu- 9Qo'n the ba'r X from the-slot 81 on `the wheel V, before the segment W. begins to act on the lantern-wheel V.

The. segment W is of such size that, at' each revolution of -the main shaftL, it will cause a'quarter revolutiouof 'the wheel V, andconsequently of the wheel 'T. This wheel T is made of adiameter twice that. of the wheel S; consequently, the quarter revolution of the wheel IJ causes a half revolution of the wheel S and of the crank-shaft It, thereby changing the harness N and O.

The notches 81, in the wheel V, are so arranged that h strike the projections g q of the slides d rl, and force said. slides down, and 4by reason offthe action of the This muses a quarter turn of Ailieltieuls o b "onvv the The'harrieseframcs N'and 0 are of the general form' ,These harness-frames are'arrangcdto slide up and upright, Di, and has its outer end turned at right angles vard Y, thus serving to keep the pin 90, in the bar X, The lowercnd of the bar X has thellat part-turned the thread 71, and the end of the wire is put through a hole, 77, in the end of the shuttle, when' the cone 1 70 istnrned down into the posit-ion shown in figs. 3., and

theshnttle is readyfor operation.

` The inout-h of hole 77 in theshuttle is rounded hori u zontally, as indicated by dotted lines in g. 3, so as' not to eut or kink the filling-wire;-

The filling-spool 72 is of the form shown in fig. 4, and has a pin or exis, 75, at one end, and hole, 7 4, with a pin, 76, therein,which projects beyond the end ofthe' spool, anni forms a Din or-axis'for the other en l of tlxe spool 'it the spiral spring 97.

It is readily seen that by pressing down .the collar 73 until itstop is flush with the end oi' the spool, said spool can readily be inserted in the shuttle n, as seen in figs. 3, and that when so inserted, it will be` re tained in that position, and be prevented from recoiling` .by the elasticity of the filling-wire, by reasonV of the 'tlonof the 'spring 97 on the collar 73.

Itis evident that, insteadof using the'fiange l:5 on the tube a. Islot' cut in the tube :may be used, the bearings p p, in'this case, having projections'orpins in their inn'er sides, which wonldslidein the slotsjn the tube lli-the object of the flanges or slots in. either being to prevent the tube b from turning;A Also, that slots could be used in the head b2, andthe' tubo gb, inf,

stead of flanges b lf, the holeso o,- in the shuttle-1i', in`

thiscase having projections or pins' oo', instead of thev A.slots o o, as now shown'. -.Eaving thus fully described my invention,
